The Weak Axiom of Revealed Preference (WARP) needs to be included. 70.111.248.60 02:41, 19 April 2006 (UTC)

[edit] theory has a problem

revealed preferred only means, "at least as good as." Not better than. So you have to have the concept of the consumer choosing A and not being indifferent between A and B to say that A is preferred to B. However, revealed preferred to is often stated so we don't know of B is just as good as or not. I don't see a great way to include this without overhauling the page. Before I do that, do others agree? Pdbailey (talk) 23:55, 13 March 2008 (UTC)

You're right. I've reread the Mas-Colell, and the axiom is stated this way : if x and y belong to B and x belongs to C(B) (the choice correspondence), then for any B' with x and y belonging to B' and y belonging to C(B'), we must also have x belongs to C(B') —Preceding unsigned comment added by 91.163.195.76 (talk) 21:25, 21 May 2008 (UTC)
